On Saturday, Oct. 21, the USS Constitution Museum will host a public celebration -- complete with a birthday card to the ship that visitors can sign -- to honor the milestone. The museum in Charlestown Navy Yard will welcome visitors to live entertainment, free games and activities and several food trucks.

From 11 a.m. to 4 p.m., hands-on activities will include creating paracord "survival" bracelets for troops overseas, building mini-ships, and other games. Rangers will also offer free hourly tours of the USS Cassin Young, a destroyer built in 1943.
